Lilie characters of reference like or similar parts throughout theseveral views of' the drawing, in which The cylindrical pump casing (1)is formed with a cylindrical bore (2) extending longitudinally andeeeentrically thereof. Mounted for reeiprocation in the bore (2) of theeasiiugT are cooperating members (8) type designa-te and (4); the member(3) constituting the pumping element, and-.the member (4) a floatingdisplacement chamber and valve eut-olif. The pumping; element is formedwith a shank (5) having a lat side (G) and an ereuate side (7), andextending from the shank (5) is a Stem (8) to which is pivoted theoperating lever of n power unit (not shown). A link connection (l0)which pivotalh engaged with the end elf the lever (9) and with a bracketing face of the web (13) connecting the two semi-cylindrical, drumshaped ends 14) of the combined floating displacement chamber and valvecut-off (4). The flat side (6) of the member (3) rides upon flatfriction surfaces provided on the ends (14) of the member (4),consequently the assembly of the two members forms a cylindrical pumpingunit which is freely reciprocable within the bore (2) of the casing (1).Suitable compression rings (15) are carried by the ends of the member(4) for an obvious pur-- pose, and packing glands may be utilizedbetween the casing (1) and the unit comprising the members (3) and (4).

Formed iii the casing (1) medially of its length is an inlet port (16)with which is adapted to register a corresponding port (17) in the webof the member (4) and in the neutral position illustrated in Figure 1,both ports (16) and (17) are in registry and are closed by the pumpinghead (12) of the member (3). An inlet pipe (18) discharges throu h theport (16), and is provided with a ap valve conventionally illustratedand designated by (19), and designed to prevent return of the pumped,ysubstance under reduced suction. A, In the neutral position'shown inFigure 1, the pumping head' (12) divides the space between the ftwo ends(14) of the member (4) into two chambers hereinafter designated Ay andB. The member (4) is normally maintained in the neutral position byopposed springs (20) which bear against the ends thereof. Springs (20)are carried by pins (21) which are slidably mounted in openings (22) inbrackets (23) and (24), and such openings are countersunk as at (25) toreceive a portion of the normal length of each spring. Each bracket isalso formed with a second opening (26) which is adapted to receive abolt (27) for nounting the brackets on lthe ends of the casing i with abody (28) provided with gnoovcd edge for receivinrr the discharge pip'e(29) of the pump, anda laterally and angularly extending arm (30). Thefree end of the arm is angularly cut down as at (31) so that when thebracket is mounted upon the end of the casing 1) in the manner shown inFigure 3 the flat side (6) of the shank of the member (3) will ride uponand be supported thereby. The bracket (24) is formed with a body (32),and a lateral arm (33) which extends at right angles to the body and isadapted to support the opposite end of the shank (5) of the member (3).It will be noted that the body (33) rises above the Varm (32) thusaffording a guideor the shank (5).

Formed iii the casing (1) arc outlet ports (34) which are closed in theneutral position shown in Figure 1 by the ends of the The bracket (23)is formedil )1H member (4), and such ports communicate with thedischarge pipe (28) heretofore mentioned. In th fore all the ports ofthe pump are closed, but as the member (3) is ymoved toward one end thesubstance to be pumped is compressed in the direction of movement and asuction is created behind the pumping head (12). In Figure 2 is shownthe position of the elements of the pump at the completion of one halfof a against the resistance Vcycle chamber VAia-completely emptied, and

a high degree of suction is created in chamber B. Upon the (16) and (17substance to e pumped is drawn quickly and with great force from thepipe (18); the ports are then moved out of registry and compression inchamber B with proportionately increased suction in chamber A follow-.From the foregoing it is believed that tire operation of my pump will beapparent. The advantages of such a` structure are manifold, but it isobvious that constant movement of the head (12) and port (17) withrespect to the port (16), and ofthe eil-ds (14) with respect to ports(34) will absolutely prevent the accumulation of clogging matterirrespective of the impurities or of the inherent nature of thesubstance y gurthermore, my pump is exy gly e ective due to the completedispy tnement of substance, and the attainment of an almost perfectvacuum through the absence of air pockets. It is also emphasized thatthese advantages are accomplished without the use of fragile valves, andother parts liable to get out of order or broken.

A slightly modified form of my invention which is especially adapted fordeep well pumping is illustrated in Figure 7. In this form the member(3) is provided with a plurality of pumping heads (12), which operate inmultiple chambers formed by the utilization of a plurality oi members(14) on the member (4). In the present" instance there are two pumpingunits, each having associated therewith intake and exhaust poi-ts suchas have nection with In my deep well pump, however, the intake e neutralposition there-- cycle of operation. Ton complete the partial cycleillustrated in F ig#L lT e com-v in the chamber A acts tov return strokethe parts` come into registry and the"V been described in con? theprincipal embodiment.

`ocated in the direction iis and exhaust ipes extend longitudinally of,and within, t e walls of the casin (l) and outwardly from the respectiveen s thereof. It is also necessary to utilize but one `s` ring (20) asthe weight of the movin partis` is suicient to accomplish the desirepurpose.A

However, two springs may be used 1f found desirablethe other springbeing shown in dotted lines. The ump casing is preferably mounted by all ty fitting conventionally shown here in otted lines also. Thepeculiar character of m .pump makes it particularly adaptable or deepwell pumping in that it is not onl inapt to clog,

ut lts action is positive an the pumping operation completed withmaximum eiiiciency, on both the upward and downward strokes.

In Figure 8 is shown a pipe connection which I have found it expedientto utilize when it is desired to use m pum as one of the ratio mixingtype. evera different kinds of substances may be pumped at the same time2y utilizing the type of my pum shown in igure 7. This is accomp ish busing multiple intakesone foreach cliamber--and pumping a differentsubstance into each chamber. Thus, by connecting my present fitting tothe discharge ports all such substances are correct y mixed, and proortions ma be Varied if desired by modi cation of t e respective intakesor the chambers.

While in the fore oing there has been illustrated and descri ed suchcombination and arrangement of elements as constitute the preferredembodiments of my inven` tion, it is nevertheless desired to emphasizethe fact that interpretation of the invention should only be conclusivewhen made in the light of the subjoined claims.
